. SPECIFICATION forming part of Letters Patent No. 633,924, datedSeptember 26, 1899.

' Application iiled June 29,1896. Serial No. 597,437. (No model.)

Be it known that I, HORATIO R. SWART- WOOD, a citizen of the vUnitedStates, residing at Tracy, in the county of Lyon and State of Minnesota,have invented certain new and useful Improvements in VVindoW-SashHolders and I do hereby declare the following to vention, such as willenable others skilled in the art to which it appertains to make and useup-and-doivn movement of the sash can be the same.

My invention relates to sash-fasteners. j My object is to provide animproved sashfastener which will be adapted to hold the sash in raisedposition in a highly-superior manner and yet allow quicker and easiermanipulation of the latter.

Having this object in View, the inventionl casing or lhousing, and Fig.5 is a vertical section taken through the casing andrack.

A designates the ordinary window-sash frame, and B the window-casing. n

The numeral 1 designates a rack `which is preferably constructed of aribbon of metal crimped into proper shape, and this rack is sunk in theface of the Window-sash and is held in place by fastening devices 2.

The numeral' 3 is a rectangular housing or casing having an innerface-plate 4c. The body 3 of the casing is sunk in the Window-casing,with the face-plate lying adjacent to the rack heretofore designated,screws 5 being ernployed to hold the casing in position. The face-plateand casing are provided With a vertical elongated slot which is incommunication With another cylindrical opening 7, that leads to theouter face of said casing. In

the upper portion of the vertical slot :is a pinion 8, which is suitablyjournaledin the casing or housing y3 in such manner that its teeth kger10 loosely passes.

had. `Aswill now appear, however, I employ improved means which isadapted to normally keep this spring in engagement with the pinion, sothat the latter is locked.

There is a plunger l0, which lies iu open-l ing 7 and has its inner endbifurcated, as

"shown at 1l, the release-spring lying in this bifurcation. One portionof the bifurcated end is formed into an inclined cam 11, which engageswith thefreeend of the release-spring and holds the same in engagementwith the pinion. The plunger is also provided with a`transversely-eXteriding limit-pin 12.

I employ two screw-threaded bolts 1li-and 14, which are secured forabout half their length Withincasing 3 in such manner that lthe otherhalf projects through the outer face of said casing in the manner shown,adjusting-nuts l5 and 16 being provided. There is au adjusting-bar 17,which is free' to slide on the outer ends oi' the bolts between'thecasing and the ends and through which the plun- A coil-spring 18 encircles plunger lO and is interposed between adjusting-bar 17 andlimit-pin 12, whereby said plunger is normally forced inward and`against release-spring 9, Vforcing theflatter into engagement with thepinion and holding said spring locked. ,By turning the nuts 15 and 16one way or the other the adjustingbar may be moved forward and thespring compressed, or it may be allowed to move outward, therebydecreasing the tensionof said spring.

The-operation is as follows: Let it be assumed that the window-sash isdown and it is desired to raise the same and hold it at any desiredheight. The plunger rod is first pulled outward `against the action ofthe coilspring, thereby allowing the free end of the release-spring tospring out of engagement IOO- with the pinion. The window may now bcraised, as the pinion is now free to rotate and mesh with the rack onthe window-sash as the latter is 'moved upward, the plunger beingmeanwhile held retracted by the operator. As soon as the desired heighthas been reached the plunger should be released,where upon thecoil-spring will force said plunger back, thereby causing the earn 1].to Contact with the release-spring and push the free end of the latterinto engagement With the pinion. It will be observed that the plungerlocks the release-spring and pinion together, asit were7 and thusprevents the window-sash from descending. When it is desired to lowerthe sash or raise it still higher, the operation may be repeated. t

My invention is adapted for use in connection with any style of windowsash and fraine and may be readily applied thereto Without materialdefacement; but it is peculiarly adapted for use in connection withrailwaycar Windows which may be easily inanipulated, thereby obviatingthe annoyance heretofore experienced in the use of such windows. Y

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a sash-fastener, the combination with a window-sash and a racklocated thereon, of a rotatable pinion, a fiat releasing-spring havingone end fixed and one end free, and a springfpresscd plunger having abifurcatcd ond straddling the releasing spring, said plunger beingadapted to hold vthe free end of the releasing-spring normally in lockedengagement with the pinion and said plunger being adapted for retractionto allow the releasing-spring to throw itself out of engageinent withythe pinion.

2. In a sash-fastener, the combination with a Window-sash and a'racl;located thereon, of a rotatable pinion, a flat releasing-spring havingone end fixed and the other end free, a plunger having a bifurcated endstraddling the releasing-spring, an adjusting-bar loose on said plunger,a coil-spring encircling the plunger and interposed between theadjusting-bar and the bifurcated end thereof, and inechanisinforadjusting the adjusting-bar, said elements being so disposed and relatedthat the plunger' normally keeps the free end of the releasing-spring inlocked engagement with the pinion,and said plunger being adapted forretraction to allow the releasing-spring tothrow itself out ofengagement with the pinion.

In testimony whereof I have signed this specilicationin the presence oftwo subscribing witnesses.

HORATIO R. SlVARTWOOD.
